Incorrect calculation fo Handicap (instead it is based of a fictional Garmin Handicap)

Minor Correction: There is a page on the Golf App, which does show the fictional Garmin Handicap in the WHS format. However if i want to edit the handicap in an individual game i only can enter / correct full numbers.

My Stableford-Points are being calculated based of a Handicap, which the Garmin Golf App has decided to give to me, instead of my real Handicap. This "Garmin Handicap" can be found somehwere in the App and does not seem to have the current World Handicap Format (only full numbers like 41 are displayed instead of my 39.3).

This is really frustrating especially since i am able (and did) enter my Handicap on the watch (Approach S62) and specially selected a scoring based on Index & Slope.

It would be nice if the Handicap would be managed through the App and is synced to the Watch for the display & calculation of strokes during the games as well as the calculation of points after the game.

To make things worse I did switch phones and noticed that the game i played is no longer recorded as activity. (The checkbox on the phone is stil set.)

I also have the same question because I have experienced confusion around how Garmin is handling handicap values and Stableford scoring. The difference between the handicap entered manually on the watch and the handicap that the Garmin Golf App appears to calculate is not very clear. If a player already has an official World Handicap Index, it would make sense for that value to be used consistently across the app and the watch instead of relying on a separate Garmin-generated handicap that may not match the current format or decimal values.

I would also like to understand the correct workflow for managing handicap information between the Garmin Golf App and devices like the Approach S62. It seems like the app should be the main place to update the handicap and then automatically sync that information to the watch for score calculations, stroke allocation, and Stableford points. I have the same question about activity history as well, especially when changing phones or reinstalling the app, because losing recorded rounds after a device switch can be frustrating. I’ev also seen people discuss how stats and progression systems work in games such as jenny minecraft, where keeping player information consistent across different parts of the experience can also be important. Hopefully someone can explain whether there is a setting that needs to be enabled or if this is a limitation with the current Garmin Golf syncing system.
